Suspect's son unhurt during shooting that killed three people Sunday

Three people have died in a shooting in northwest Austin on Sunday, according to Austin-Travis County EMS.

The identities of three people police say were killed by a former sheriff's deputy in Austin on Sunday have been identified as his ex-wife, stepdaughter, and her daughter's boyfriend. The couple's son was not harmed in the shooting, police say.

Authorities arrested 41-year-old Stephen Broderick on Monday following an overnight manhunt. Police said Broderick was arrested without incident along a rural road in an Austin suburb approximately 20 miles from the scene of the shooting.

Authorities identified the victims in the shooting as 34-year-old Amanda Broderick, Broderick's ex-wife; 17-year-old Alyssa Marie Broderick, his adopted stepdaughter; and 18-year-old Willie Simmons III, the teenager's boyfriend.

Broderick was carrying a loaded pistol in his waistband when he was apprehended, policed said. A motive for the shooting has not yet been revealed.

According to Austin police, the shooting happened at about noon Sunday in a popular shopping area known as The Arboretum. It was there where police said they found the victims lying near two vehicles.

Police said Amanda Broderick and her ex-husband were meeting for a scheduled visit with their son, who they said was unharmed during the shooting.

Simmons and Broderick's 17-year-old daughter were students at Elgin ISD. Both were described as standout students and athletes by school officials.

Alyssa Broderick had been a member of the Elgin High School basketball team and enrolled in an early college program before she withdrew from the school district last October, Jodi Duron, the school superintendent, said.

Simmons was captain of the football team, and he had recently been recruited to play college football at UNT.

UNT head football coach Seth Littrell said on Twitter, "Willie Simmons was exactly the kind of young man that every college coach wants to recruit. His athletic talent was obvious, but his personal character, his selfless attitude and his passion for life made him a natural leader and the perfect teammate."

Broderick, a former deputy with the Travis County Sheriff's Office, he left his job after he was arrested last year on a sexual assault charge, prosecutors said.

Court records show that a protective order on behalf of his ex-wife and two children had been filed against Broderick following that arrest in June.

Broderick had been required to surrender his firearms and wear an ankle monitor to track his whereabouts following his arrest, according to Travis County prosecutors.

Police did not say where Broderick got the weapon used in Sunday's shooting.
